Answer:
The correct answer is C) Hortatory
Explanation:
In this example, we can see that the government is trying to 'strongly urge' people to take steps and reduce pollution and litter on the highway.
This is an example of a Hortatory technique of policy enactment.
An incentive policy enactment might be giving someone a 'reward' by following something. E.g. in many countries the government provides you tax incentives if you reduce your home garbage.
An Authoritative technique would be to fine people for littering on the highway. This is also a useful way that is used in some circumstances .e.g. if a car crosses a read light.
In this case, a hortatory policy takes time to get hold of, but can eventually reap a lot of benefits in the long-run.
